SPINDLE-DRIVING DEVICE FOR SPlNNING-MACHlNES.

SPECIFICATION forming part of Letters Patent No. 446,751, dated February 17, 1891.

Application filed August 20, 1889. $erial No. 321,340. (No model.)

.To all whom it may concern.-

Be it known that we, SAMUEL J AMES and JEREMIAH K. SANDERS, of Lebanon, in the county of Laclede and State of Missouri, have invented a new and useful Improvement in Spindle-Driving Devices for Spinning-Machines, of which the following is a full, clear, and exact description.

Our invention relates to an improvement in banding and tension devices for spinning and twisting machines.

The object of our invention is to provide a simple and economical construction and arrangement of parts for the banding and tension mechanism of aspinning-jack and yarntwisting-machine, whereby the series of spindles in a section of the machine will be simultaneously rotated in the same direction by a single band, the tension of said band being automatically regulated in an efficient manner with a new and improved tension mech anism.

A further object is to provide the novel tension device hereinafter mentioned with a self-feeding oiler, which will enable the apparatus to be run longer without stoppage than can otherwise be effected.

lVith these objects in View, our invention consists in the novel construction and combination of the several parts, as will be hereinafterfully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is an end elevation in section of the device. Fig. 2 is a front elevation of the spindles and their supports. Fig. 3 is a top .plan view of a section of a spinningjack,

the spindles being shown in section, and Fig. 4 is an enlarged detached sectional view of one of the important features of our invention.

A is the frame of aspinning-jack, of which A and A are parallel front rails, which support the series of spindles B B B which are spaced apart and seated in suitable boxes f, which receive their lower ends and permit the spindles to rotate therein. On the upper rail A supporting-boxes g are fixed to receive and support revolubly thebodies of the spindles.

'At a proper point rearward of the gang of spindles a cylindrical band-roller O is supported by its journal. ends 6 on the frame of the jack, which roller extends throughout the length of the spinningnnachine, and is revolved by any suitable means. (Not shown.)

It is preferred to arrange a convenient nu mber of the spindles in a section. lVhile the number may be varied, it is found advantageous in a jack having an aggregate number of spindles equal to two hundred and forty to run twenty-four spindles together. The end spindles B B have the whirls c c and c 0 which whirls are each formed with two belt-grooves, as shown.

The intermediate spindles B of a section are furnished with whirls c, which are singly grooved to receive a belt. A belt-tightener or tension device is furnished to regulate the draft of the belt G. Said tension-regulator consists of a guideway D, which is made extensible by its sup port on a slotted bracket D to which it is bolted at b, the opposite end of the guide way being furnished with a flange D, that is bolted or otherwise attached to the jackframe A.

The guideway D is preferably constructed as a flat metal bar havinga longitudinal slot formed in it to receive the sliding block E, which is loosely fitted therein in a manner to prevent displacement and allow it to re ciprocate freely throughout the extent of the elongated slot it lies in.

On the sliding block E a grooved whirl l" is supported to rotate by mounting it loosely on a stud-bolt a which is firmly inserted in the sliding block and secured in place by a nut a. (See Fig. 4.) Upon the upper end of the stud-bolt'ct an oil-cup a is formed. It, constituting the head of the bolt, retains the whirl F from displacement. The oil-chamber of the cup at is formed as shown, and axially central with the body of the bolt a a feedhole 7L penetrates the bolt a short distance and then intersects a transverse hole 2", which is in proper position to convey oil to lubricate the whirll \Vool or cotton in small quantity is inserted in the feed-channels llIOlltioned, which rest-rains the flow of oil and graduates its delivery to continually supply the lubricant as it is needed.

The bracket D which supports the front end of the guideway D, has its slotted projecting portion inclined from a horizontal plane downwardly, thus affording a proper support' for the guideway, which is downwardly inclined from frontto rear end, as shown in Fig. 1.

A coiled spring I is attached to the front portion of the jack-frame, or to the bracket D as shown, by one of its ends, said spring extending.rearwardly below the guideway D inline with it.

The rear end of the spring I is connected to a cord or other flexible strand J, which is passed'around the grooved pulley J, that is pivoted'on the lower end of the guideway-bar in its slot, and said cord beingreturnedabove the guideway is attached by its other end to the sliding-block E at d. the springl to the sliding blockE by the cordJ,.asstated, will draw the block toward thelower end of the guideway.

An endless belt G is-provided to drive all the spindles of asection at one time in the same direction. To effect this operation the belt is given a half-turn over the grooved Whirl F, which is mounted on the sliding block E, as shown in Fig. 3. It is then ex-' tended diagonally towardtlieend spindle B, and around the lower whirl'c' of said'spindle, thence rearwardly over the cylindrical roller 0 and'returned, as at 2, to the upper whirl o of the spindle B. From the whirl c the belt G is extended rearward and'upward, passing around the cylinder 0 and bearing on its rear'half', thence diagonally sidewise, so as to engage the whirl c on the first spindle B, nearest the end spindle 13. From the whirl of the said spindle B the belt is'drawn straight back, as at at, and passes around the cylinder 7, then forward diagonally, as at 5, around thewhirl of the second spindle from the end spindle B, then straight to the rear and upwardly, .to againpass aroundthe rear half of the cylinder, as shown at 6, Fig. 3. The belt is arranged'to successively engage the series of whirls of the several intermediate spindles B inmanner similar to that already explained, and at the end spindle 13 which terminates the section of the spinning-jack driven by one endless belt, the belt G, which has been diagonally extended from the lower side of the cylinder 0 toengagethe upper whirl 0 as at 7, is thence rearwardly and upwardly drawn, as at- 8, to pass over and around the cylinder, thence forward and around the groove in the'whirl on thespindle B and thence diagonally to an engagement with the whirlF on the sliding carriage before mentioned;

It will be evident from the description The connection of given that the endless beltG will transmit rotary motion from the cylinder C to all of the spindles 13 B B of a section, which may be any convenient number of spindles.

In arranging the belt G it is so proportioned in length relatively that the sliding block E will be drawn up near the top of the guideway D, so that the full contractile force of the spring I will be available to take up slack which may occur in the belt from use.

A number of manifest advantages result from the novel construction and arrangement of parts herein described. tial are that the number of belts used to transmit motion to the spindles is reduced;

the tension device is automatically and eco-' nomically oiled; the tension arrangementwill beeffective for a long time, avoidingthefrequent cutting of thebelt to take up slack, and further, themotion of the spindles-in" a section being transmitted thereto by asingle belt is-more regular than in ordinary spinning-jacks using a number of independent belts for the purpose. The tension-guideway D being extensible, its length maybe ad justed to suit jack-frames of dilferentdiinensions considered from front to rear of" same, which is of advantage where frames'of varied width are fitted'up to use our improved tension and handing device.

Having thus fully described ourinvention, we claim asnew and desire to secure by Letters Patent 1.
